In the textbook of People's Education Press, after learning compulsory 2, it is generally compulsory 3 and compulsory 1, followed by discrete mathematics, compulsory 2, probability theory and mathematical statistics, compulsory 3, engineering mathematics, statistics and compulsory 4. Ellipse will be studied in the elective course 2- 1 chapter 2 conic curve and equation.

For compulsory courses and elective courses, the focus of the exam is different, so we can't both spend the same time studying. If you don't have much time and energy to study in elective courses, you can do fewer questions, but you must be serious in compulsory courses. Take it seriously, especially the subjects to be tested in the college entrance examination, and pay more attention to it.
